Corpus striatum

Corpus Striatum is a part of the brain that is involved in the coordination of movement. It is a component of the basal ganglia, which are a group of nuclei in the brain associated with a variety of functions including: control of voluntary motor movements, procedural learning, habit learning, eye movements, cognition, and emotion.

Structure

The corpus striatum is divided into two components: the caudate nucleus and the lentiform nucleus. The lentiform nucleus is further divided into the putamen and the globus pallidus.

Function

The corpus striatum plays a crucial role in the planning and modulation of movement pathways but is also involved in various other cognitive processes. It receives input from various areas of the cerebral cortex and processes it to regulate actions of the body, the emotions, the learning and the mood.

Clinical significance

Damage to the corpus striatum can lead to a number of movement disorders, such as Parkinson's disease and Huntington's disease. These diseases are characterized by the loss of motor control and are often accompanied by cognitive deficits.
